“Zombies” are just an unconscious-mind metaphor for unreasoning ideological/prejudice mobarchy “rabies”.

Proletariat/populist ( left/right: they are equivalently-destructive ) dictatorship highjacked your country?

Rampaging mobs butchering & burning your books, your infrastructure ( shooting electrical substations, hospitals, school-lunch-programs, civil-rights protection ), & your citizenry?

That’s what real “zombies” are.
